c'onstrfict my device-that I may takeiaidvanin'g bolts, and a'plurality of bolts are emtageof the so-called icountebcurrenthow ployed for apurpose that shall appear later, ofliq-uids,"whichJI believe to be the most efiiand while it"may appearr' that a great numcier t condenser praqtice; i I v V 'ber of boltsare used, Ido thisfor the rea- 45 Withthese"ob ets' in view-,and'others not son that my device must/be tight, and yet I prefer not to use packing between the parts, but to bring the parts firmly together, metal to metal. This not only simplifies the construction, but materially aids in assembling or disassembling the structure.

At the other end, the left end, in Fig. l, of the drawings, I provide another end plate, as shown at 23. This'plate is, 'in all respects, similar to the plate 1, and is provided with a dome 24.

The separator member is of a shapesimilar to the member 25. In Fig. 3, the separators are not shown corrugated, and while they may tions, I prefer that they be corrugated forthe '1,

reasons set forth.

And now, when the device is assembled in? the manner described, oil may be introduced 7 in the direction of the-arrow"-A, and will flow downward in alternate spaces, as indicated by the arrow 0, to be discharged in the direction indicated by the arrow B. Waterwill be introduced through the pipe 14 and in the direction ofthe arrow G, and will flow upward'in alternate spaces, as" indicated by the arrow WV, to be discharged through the opening 11, showninFig. 2.

While I have referred continuallyto oil and water, I, of course that any cooling or breaking medium may be employed in lieu of the water, and any fluid or gas medium may have its temperature reduced or raised by causing. it to 'pass through one of my devices, and in counter-relation to the passage of the cooling medium, or heating medium.

While 1 have described thisidevice at a means forremov ng theheat from oil 'or I sections may 60' 1 and 23, the number being deterother fluids, it will be" just as readily ei'nployedfor the purpose of'imparting heat to oil, or other fluids, if such is desired.

In Fig. 6, I show a filtering'cap. This cap is intended to. be used asfa substitute'for either of the end members, 1 or 23, but would be placed where the oil enters my device, so that the oil will beliltered, before passing through my device.

While the dome teriorally of my structure,

projectsoutw ard, ex-

I am about to describe. I

Arranged between the plates 1 and 23, are

each operates in an exactly similar manner to all other sections, I-will describe the construction of only a single section, desiring it understood, however, that any number of be" introduced between the plates mined entirely by the desired capacityQOr operable efficiency of the completed device.

Only a fraction of all the liquid-passes be tween each segment.

Each section consists of a base member 25,

be made with or without'corrugaof lugs forme desire it understood appended claims,

the dome24' projects inwardly and toward members, which having a plurality of lugs formed integrally therewith, as shownat 26, 27, 28 and 29, and these lugs are so aositioned that together, and with the pipe ttings already described, and separators, they form a passage or conduit throughout the device, and through which the oil and water are free to pass. As shown in Fig. 4, a portion of the base member is cut away to produce a passage from theperforation in'each lug to the center, two of these passages being arranged on one side of the member 2.5, and for' a purpose that shall appear later,

At Fig. 5, I show a disc or separator member. This discomember may have a plurality d integrally therewith. As shown, in Fig. 5, this disc member, and in fact, all of the separators -31, may be corrugated forthe purpose of increasing the effective area thereof. 4

The filtering capis provided with an inlet passage 38, through which the oil enters-t0 be received into a which conduit connects with a conduit. 40in the cap member 41. The oil passes interiorl-y of a filter, which maybe a cylindricalmember 42 having a soreen 43 atthej innermostend thereof. The spring44 urges the filter upwa on th upp rt n bolt45 "T Q Pa ing through he filter andf'screen43, nowienters my device through the passage 46, and valve47. I'" InFig. 4, I showa section member,1having a channel 48 produced therein. A perforation 49 allows water to'pass into this channel, thus producinga water seal between each sectional member, which is desirable, if the device is to be used for ammonia, or other fugitivegaseskf It will be understood that the size era-1i parts may be changed at will, to increasegor distributing conduit 39,

decrease, the capacity ofthe heat exchanger;

decreased or increased, and other modifications maybe made within the scope'of the without departing from the principle, or sacrifici t advantages of this invention.

Having carefully" fully described invention, what I claim and deire to "secure by Letters Patent is 1.-A heat transmitter, having means for increasing the effective ar'e'ath'ereof, said means comprising a plurality of sections, a V A plurality of dome-shaped members associat-' ed with each said section and projecting thereinto, and end members, onesaid member having an outwardly projecting dome and the other said member having an projecting dome, and means for securingthe whole in operative position.

2. A heat transmitter comprising a plurality of end members'oppositely domed,.a jpluinwardly .rality of sectional members-arranged.there- 7 between, each said sectional. member being provided with lugs, having passages therethrough and transverse passages therein, separators between said sectional members, being provided with passages communicating from the first said passages in the lugs to the space between alternate pairs of separators. r

3. A heat transmitter comprising a plurality of end members, each said end member being dome shaped and each said end member being provided with corrugations to increase the effective area thereof and a plurality of section members between said dome shaped members.
